MATRIX-DISTRIBUTING MECHANISM.

Specification of Letters Patent.

Patented Mar. '7, 1916.

Application filed June 15, 1914. Serial No. 845,085.

'State of Connecticut, have invented a certain new and useful Improvement in Matrix-Distributing Mechanism, of which the following is a full, clear,'and exact de'- scription.

Several prior patents disclose multiple magazine typographlc machines which are provided with means designed to automaticallydistribute, to the magazines in which they belong, matrices which are constructed with font distinguishing characteristics that cooperate with said distributing means to produce this result. But in all such machines, any given font of matrices will, of necessity, be distributed to the magazine which occupies a certain position in the machine,that is to say, a position which is associated with and determined by the said font distinguishing structural characteristics of said matrices. In other words, a magazine which contains a font of matrices having certain distinguishing structural characteristics, must always occupy a definite'position in a machine which is organized to cooperate with said structuralcharacteristics of the matrices to determine and effect their distribution. This imposes restrictions upon the use of a font of matrices and consequently upon the use of the multiple magazine machine to which they are adapted, which is sometimes very objectionable. For example, a printer may have a favorite font of matrices which he desires to use in his machine in conjunction with numerous other fonts of matrices. But if this favorite font be constructed for distribution to a maga-- zine occupying a certain position 1n the ma-' chine, he cannot use it in'conjunction with another font which is also constructed for distrlbution to a magazine occupylng the same position.

The object of this invention is to endow the distributing mechanism of a multiple The invention is shown in a form adapted especially for use in connection with the multiple magazine typographical machine which forms the subject matter of an application Serial No. 795,398, filed by myself and E. S. Goddard October 16, 1913. The adaptation of the invention to this particular machine, fortunately, involves very slight structural'changes in said machine, and very slight changes in the matrices to transform normal matrices to specialized matrices, z. 6., matrices adapted to be distributed at will into either of two or more magazines. In fact, the changes in the machine construction requiredare so slight that it has not been thought necessary to show any considerable part of the distributing mechanism, except the parts which involve said changes. As will be seen from the appended claims,- however,the invention is much broader than its mere application to this particular machine.

Any embodiment of the distributing mechanism which forms a part of the typographic machine which is shown and described in said prior application involves the provision of numerous groups of switch gates. The number of such groups required depends upon the number of magazines in the machine and the number of channels in each magazine. In a machine in which, like that shown in said application, there are four magazines, each adapted to contain one complete font of matrices, nine groups of gates are required. The two lower groups are those which determine which of the magazines the matrices shall go into. Associated with each group of gates is a pair of endwise movable feeler rods, which are the matrix engaging parts of the gate operating mechanism; and these several pairs of feeler rods are so grouped that any matrix which is moved in a fixed path toward their ends by the mechanism heretofore provided for so moving the matrices, may engage and move any desired combination of such rods, depending upon the diiferentiated structural characteristics of said matrices. A normal matrix, 2". 0., a matrix which is constructed solely for use in the machine of such prior application is hole-punched in such wise that it presents a hole in alinement with one or the other rod of each pair of feeler rods. herefore, when such a matrix is moved against the ends of the group of rods, it may move one, and only one of each pair of rods,the other rods of said pairs of rods being free to move in the reverse direction through the opposed holes in the matrix.

Each pair of feeler rods is associated with av group of switch gates through intermediate mechanism by which said group of switch gates is caused to move in one direction or the other, depending upon which rod of the associated panof feeler rods is moved by contact from said matrix.

The two upper pairs of feeler rods are those which control the operationof the two lower groups of switch gates,that is those groups which determine the magazine into which a matrix shall be delivered. In the construction shown in said application the movement by pressure from a matrix of the rear feeler rod of next to the upper pair of rods. 0. ti e eighth pair, will cause a forward movement of the ates of the next to the lower grou s of 9'ates,2. e.,the eighth group of gates. Wherefore said gates, after being so moved, will cause any matrix to pass behind them and therefore into one or the other of the two rear magazines; whereas, if it is the front feeler rod of said pair which is so moved by pressure from a matrix, the corresponding grou of gates will be caused to swing rearward and therebv direct the matrices in front of them and therefore into one or the other of the two front magazines. If the rear feeler rod of the upper pair or ninth pair of feeler rods is moved by pressure from a matrix, the lower or ninth roup of gates will swing forward; but, if the front feeler rod of said air is so moved, the lower group of gates will swin rearward. In the former case, matrices which were delivered in. f ont of the gates of the eighth group, will be directed into the front magazine of the front pai .that is to say, into the first ma ga zine. were delivered toward one of the two rear magazines of the eighth group of gates will be directed into the front magazine of that hair, namely, the third magazine. In case the ninth grou of gates are swung forward, the matr ces will be directed toward the second .o fourth magazine, according as they we e direc ed in front of or behind the gates of the eighth group.

Now, in all of the respects above pointed out a machine embod in the present inventic-n is or may be exactly like the machine of said prior application. In fact, the drawings forming a part of this application have been const ucted upon the assumption that thein ention is to be embodied in the machine shown in said prior ap lication. and that all parts of the distributing mechanism required in a typographic machine, which are not shown in the present drawing, are

Whereas those matrices which exactly like the machine of said prior application. It is, in fact, only necessary to change said machine in the following particulars, viz. one or the other or both of the two upper pairs of feeler rods, instead of and therefore subiect to the engagement I thereby, may be alined with diiferent parts of the surface o-fsaid matrices when the latter are moved toward the ends of said rods by such mechanism as has heretofore been used for so moving said matrices.

In the drawing, Figure 1 is a front elevation of so much of a mu tiple magazine typographic machine as is concerned with the present invention. Fig. 2 is a plan view partly sectioned of the mechanism shown in Fig. 1. Fig. 3 is a view from the left end of the group of feeler rods shown in Fig. 1. Fig. 4 is an enlarged plan view of the feeler rods and the mechanism by which a matrix is caused to operate them, and also of the mechanism by which the feeler rod housings are moved. Fig. 5 is a. vertical sectional viewin the plane of line on Fig. 4. Fig. 6 is a side elevation of a normal matrix. Figs. 7, 8 and 9 are similar views of the upper part of three different forms of specialized matrices, adapted to be used in connection with the in ention.

Referring to the parts by letters, 9*, 9 represent the two rods of'the upper pair. 2'. e. the ninth pair of feeler rods, namely, those feeler rods which, shown in said prior application, are associated with and control the o eration of the lower or ninth group of switch gates.

8 8 represent the next to the upper. or eighth pair of feeler rods. iz. those which, as shown in said prior application. are associa ted with next to the lower or eighth group of switch gates.

In the construction shown in the drawing each of the two upper pairs of feeler rods are mounted in a movable housing. The upper pair 9, 9 are mounted in the hous ng 10,'while the pair of feeler rods 8, 8 are mounted in the housing 12. Each housing is merely a flat bar containing guideways for the associated pair of feeler rods in which the latter are held in parallel relations. and in such manner that they may move endwise in the housing. The housing 12 rests upon the frame member 14, in which, as shown in said prior application, the seven lower pairs of feeler rods are movably mounted. The housing 10 rests upon the housing 12, and both ""of these housings are pivoted at their right ends to the frame member 14 on the same vertical pivot 15 and are independently movable. This manner of mounting the housings permits the left ends thereof, namely, the ends from which the'feeler rods project for engagement with the matrices, to be moved short distances forward and backward,-- that is to say, in directions transverse to the length of said feeler rods, whereby said feeler rods may become alined with difierent parts of a. matrix, when the latter is held in a cage 16 which is movable in a fixed path toward and from the adjacent ends of the feeler rods, by suitable mechanism. It is sufficient for the present purposes to know that this cage is fixed to a slide 16 which is movable horizontally in fixed guideways; inasmuch as this cage and its associated mechanism is shown and described in detail in Letters Patent No. 921,065.

There is associated with each housing a spring 17 which operates to move said housing forward, into the special position therefor, when it is permitted so to act. WVhen so moved, said housings are stopped in the proper special positions by engagement with set screws 18 or 19. Associated respectively with said housings 10 and 12 are the cams 25, 26, pivoted to the frame of the machine. Each of these cams is independently movable, and when suitably moved will engage the associated housing and move it back to normal position and hold it there.

Associated with the two housings are the two levers 30 and 31. The right end of the former engages in a recess 10 in the upper housing. The right end of the latter engages a similar recess in the lower housing. Pressure applied to the rear side of the left end of either of these levers will cause the lever to swing and the associated housing to move rearward into its normal position.

Fig. 6 represents a normal matrix which is constructed with differentiating structural characteristics for cooperating with the distributing mechanism when both of the two upper pairs of feeler rods are in their normal or rearmost position. That is to say, said matrix is hole-punched in such a manner that when it is moved against the ends of the feeler rods, when the latter are in their normal positions, it will engage and move the rear rod of the upper pair and the front rod of the eighth pair. In a machine constructed as shown in said prior application this will cause such movements of the eighth and ninth groups of switches that the matrix will be guided into the second magazine.

Figs. 7 8 and 9 each show a specialized matrix which has the same font distinguishing structural characteristics as the matrix shown in Fig. 6, whereby under the condi tions stated each of said matrices may be delivered into the second magazine. But each of the matrices shown in Figs. 7, 8

and 9 has other font distinguishing structural characteristics, through the action of which on the eighth and ninth pairs of 6 and 7. The points 9 and 9 at which the line 6 intersects lines a and b are the points which are alined with the two upper feeler rods when the housing 10 therefor is in its normal, 11. 6. its rear position. Therefore, at one or the other of these points a hole must be punched, so that the matrix may be slipped over the end of one feeler rod of the ninth pair, and will not therefore press against more than one of said feeler rods when the housing therefor is in the rearmost position. In all of said Figs. 6 to 9 the hole is punched at the point 9 The points 8 8 at which lines a, 7), intersect line f, are the points which are alined with the eighth pair of feeler rods, when the housing 152- which carries them is in its normal, that is its rear position. Therefor a hole must be punched at one or the other of these points in order that the matrix may selectively move one or the other of said rods as it is moved against them, when housing 12 is in its normal position. lVhen, therefore, the two housings 10 and 12 are both in their normal positions, all of the matrices shown in these four figures will produce the same selective characteristic movements of the eighth and ninth pairs of feeler rods,that is to say, such movements as will produce, in a machine like that shown in said prior application, a movement of the eighth and ninth groups of gates such as will cause the matrices to be delivered into the second magazine.

The points 9", 9 at which line 6 intersects lines 0 and (Z are the points which are alined with the ninth pair of feeler rods when their housing 10 is in its forward or special position. Therefore a hole must be made at one or the other of these points if the matrix is to be capable of selectively moving the ninth pair of feeler rods when. their housing 10 is in its forward or special position.

The points 8, and 8 at which line intersects lines 0 and d, are the points which are alined with the eighth pair of feeler rods when the housing 12 which carries them is in its forward position. Therefore, a hole must be made at one of these points, if the matrix is to be capable of selectively operating the eighth pair of feeler rods when the housing 12 therefor is in its forward position.

Fig. 7 shows a matrix which is specialized by the addition to a matrix like that shown 7 the same normal arran ement of holes which are shown in Fig. 6, but it also has a specializing hole at 8. Therefore, when the housing 12 is in its forward position the rear feeler rod of the eighth pair will be engaged and moved by the matrix instead of the front rod of said pair, as would be the case if the housing 12 were in its rear position. Therefore by having the housing 12 in special forward position when this matrix is moved against the feeler rods, there will result such a movement of the eighth and ninth groups of gates in the machine as shown in said application that the matrix will be guided into the fourth maga zine.

In the matrix shown in Fig. 9 there are the same arrangement of holes which is characteristic of the matrix shown in Fig. 6, and there are also specializing holes at the points 9 and 8 for cooperation with the feeler rods of the eighth and ninth pair of rods when both of the housings 10 and 12 are in their forward positions. If, under such conditions, this matrix is moved against the feeler rods, there will be such a selective movement thereof and a consequent movement of the eighth and ninth groups of switch gates in the machine shown in said prior application, that the matrix will be delivered into the third magazine. In fact, the doubly specialized matrix shown in Fig. 9 mav cause such selective operations of the eighth and ninth pairs of feeler rods as will cause the deliverance of such matrix into any one of the four magazines at will. If, for example, the housing 10 is locked back in its normal or rearward position by the action of the cam 25 the normally placed hole on this matrix will cooperate with the ninth pair of feeler rods and a specializing hole will cooperate with the eighth pair of feeler rods, which will result in such selective operation of said feeler rods and the associated groups of switch gates that the matrix will be guided into the fourth magazine. If only the housing 12 is looked back in its rearmost position by the action of the cam 26, the matrix will be delivered into the first magazine; while if both housings are locked back by the cams provided for that purpose, only the normally placed holes will cooperate with the two upper pairs of feeler rods, and consequently this matrix will be guided normally and delivered into the second magazine.

The machine shown and the matrices shown are constructed for such cooperative action that each matrix requiring such movement may automatically move one or both housings 10 and 12 rearward in opposition to spr ngs 13, so that when any matrix engages the feeler rods, said housings will be in the required positions for distributing either normal matrices into the magazines in which they belong, or for distributing the specialized matrices into magazines occupying the special positions for which the matrices are specialized. For example, if the machine contains magazines holding normal matrices and some or all of the specialized varieties shown in Figs. 7, 8 and 9, the two housings 10 and 12 may be allowed-to be moved by their springs to their special or forward positions. In that event, both ends of the levers 30 and 31 will project into the path of the front edges of all the matrices. In the front edges of the specialized matrices are notches 20* which are so placed as to enable the matrices to pass one or both of said levers, as required, without moving the same. A normal matrix has no such notch, and therefore as it is moved toward the feeler rods, itengages and rocks both levers 30 and 31, and consequently moves both housings rearward into the positions they should occupy to produce the desired cooperative action between the eighth and ninth pairs of feeler rods and the structural font distinguishing characteristics of the normal matrix. If, however, a matrix is specialized as shown in Fig. 7 for cooperation with the feeler rods of the housing 10 when in its forward position, and the housing 12 when in its rear position, this notch 20 'is so constructed and located in the front edge of the matrix that such edge will not engage the upper lever 30, but will engage and rock the lower lever 2-31. When the matrix is specialized as shown in Fig. 8, the notch 20 is located so that the front edge of the matrix will engage and move the upper lever 30, but will not engage the lower lever 31. Therefore. the lower housing will remain in the abnormal. position and the upper housing 10 will be moved to the normal position.

lVhen the matrix like that shown in Fig.

9 is specialized for cooperation with the two upper pairs of feeler rods when both housings 10 and 12 are in their forward positlons, the notch is made so wide that the front edge of the matrix does not engage a either levers 30 or 31.

When only normal matrices are bemg used in the machine both housings 10 and- 12 may be moved and held in the rear position by the action thereon of the cams 25 and 26. When none of the matrices being a matrix having plural sets of diiierentiating structural characteristics, each set being adapted to independently coact with the same parts of said dist "ibuting mechanism to produce characteristically diiiferent matrix distributing results.
